Now I want to talk about changing jaws, positioning jaws and bolting on jaws for safe operation.
4.1 - First, only use this special wrench to change jaws. A standard wrench will damage the chuck.
4.1 - Never leave the wrench in the chuck.. If you start the lathe, the wrench can fly out and hit you. If you actuate
the chuck with the wrench in, the chuck will be damaged.
1.3.6 - Only use jaw mounting bolts that are marked grade 12.9, with threads in new condition, and long enough to
engage a thread length 1 ½ - 2 times the diameter. Torgue the bolts to the specification as shown in the
manual
(Chuck size 170-225 M8 24 ft-lb; 265-400 M12 80 ft lb; 500-63 M16 180 ft lb.) If you over torque,
the base jaw may distort slightly and won't slide easily in the guideway.
4.2 - Always positon the inside end of the base jaw or monoblok jaw inside the "Safe" zone marked on the face of
the chuck. Don't ever extend base jaws beyond this limit, and don't ever position any top jaw beyond the
OD of the chuck more than a standard base jaw would extend when it is within the safe zone.
Demonstrate
installing a jaw, point to the safe zone.
- Finally on the subject of positioning jaws, always position the jaw to grip the workpiece as close to the start
of the jaw stroke as possible. The issue isn't that the chuck needs to operate near the start of the stroke, the
issue is that you want to have extra stroke available in case one of your workpiece blanks is much smaller
diameter than the blank you setup with. With the cylinder on this lathe, this chuck has a jaw stroke of ___".
The adjustment pitch is ___ ". The maximum jaw stroke for this chuck is ___", so with this cylinder we are
short stroking .....
(a little bit, a lot, whatever describes this installation.)
UC2 Model 180 215 260 315 400 500 630
Adjustment .189 .189 .216 .216 .216 .275 .275
Max. Stroke .27 .31 .35 .36 .39 .45 .50
So when using hard jaws on this machine:
a. ( if the jaw stroke exceeds the adj. pitch more than .040") you might find two possible jaw positions that work.
If so, choose the one that grips close to the start of the stroke.
b. (jf the jaw stroke is short) you will need to purchase a set of half-pitch base jaws and when necessary switch
with your normal base jaws to grip close to the start of the jaw stroke.
It is very important that each time you chuck a part you note if you are near the end of the jaw
stroke and risk not properly holding the part. If this happens, adjust all three jaws in one step and use half-
pitch base jaws if necessary.
(This point may be a bit confusing, so spend as much time as necessary until
everyone understands.
- Are there any questions?
Lubrication is important on any chuck. On this high-tech, high performance chuck it is particularly important.
See manual sections 5.2 and 1.3.5.
- Unless the chuck is properly lubricated your grip force might only be 50% of what it would be with proper
lubrication. You could throw parts.
- Use only ATS Systems’ KO5 grease. Grease chuck every 24 hours of operation, two shots of KO5 per grease
fitting with the chuck in the full “open-jaws out” position.
- Fully stroke the chuck (10) times after lubricating to distribute grease to internal components.
